In message 20110310065452.GE6012@pig.dieconsulting.com, "David I. Emery" writ
es:

The reason LORAN-C got killed was that DoD/DHS couldn't jam it if a
terrorist with a suitcase-nuke was trying to find his way to Congress.

Is this tongue in cheek, or do you have any actual basis

for stating that DHS was afraid Loran C WASN'T jammable ?

I have this information from several independent sources.

I wonder what the threat analysis behind this one was... making

an increasingly vital service more fragile because of what some have
called "movie thriller" plots ?

We are talking about DHS, the same people who want to see your junk
in airports, what makes you think there is an analysis and not just
security-theater involved ?
